To all whom it may concern:

Be it known that I, 'AMAND DAicRn, a citizen of the and residing at 39 Route de la Rvolte, Levallois-Perret, Seine, France, have invented certain new and useful Protective Armor ing, of wlii h the following is a specification.

This invention relates to protective armoring either in the form of separate shields to be worn by the combatants or in the form of plating for constructing shelters, protecting screens, cupolas, gun and rifle shields, or armor plating for protecting the; mportant parts of aeroplanes, dirigibleballoons andso forth. It is the object-of the invention to provide a light form of armoring suitablefor the above purposes,,and wherein a metal plate is coated and cushioned by a layer of a softer material.

According DELILLE French Republic,

to this invention armoring is composed by grouping together metal plates Specification of Letters Patent. Application filed April 11, 1917. Serial No. 161,353.

and sheetsof an elastic orplastic materia these plates and sheets are variable in number according to the purpose in view and are superposed and arranged alterna 1y.

The assemblage of one or a plurality of metal plates and one or a plurality of sheets of plastic material for 'a given surface of projectiles considerably superior to that obtained with a single plate of the same metal, size and weight.

The metal plate may' be of an suitable metal suchas steel, aluminium an so forth, according to the degree of resistance and lightness which-it is desired to obtain and forms armoring whi according to the conditions of fightingto which the combatant or object protected are to be exposed. The armor may be either inthe form of a single piece or of a plurality of pieces, which may be in the form of laminee, scales and so forth, hooked or otherwise ected one to another so as to form a soli" flexible and pliant entirety as may be required. v a

The armor plating. or shield may be made in a number of diiferentways.

For example a shield may be formed of two metal platesbetween which is nterposed the sheet ofv resilient material; in this case the projectile will first strike a metal plate. It is also possibleto place'alternately a number offinetal plates ret shieldsand sheets of te lorder tot form hi hl resfllent ma The srrsngems enr'iah wpter...bath, and then filled in unh 1 attachment.

plates and sheets may be such that the pro- I jectile will firststrike either a metal plate or a sheet of resilientmaterial. may also be formed from a single metal sheet and a sheet of resilient material.

In general, it appears to be advantageous for the projectile to be allowed to strike the resihent material first.

A form of construction which is'particularly good is that which consists of a sheet of steel placed ent material. This form of construction which will 'be described later, appears to present the highest resistance for a given size of surface and'weight'and is particularly adapted for the construction of separate protecting shields for combatants.

In the accompanying drawings, Figures 1, 1f, 2 and 3 show an example of onstruction of ashield forpersonal wear, according to this invention, formed of aplate or plates of steel alternating with sheets of re- 1 is a modification of the device shown in Fig. 1 ,Fig. 2 is a front view with portions broken away so as to show the different layers of which the. shield is composed, and

A .shield between two sheets of resili- Fig. 3 is arear view with the hooks for illustrate the v such a shield be carried or worn by a soldier.

The steel plate 1, of any suitable shape is surrounded by a metal frame 2 which may beformed' of aluminium of U-sectiOn.

The steel plate 1 thus surrounded by the aluminium frame 2 iscoated on its two sides with sheets 4 of resilient material, and the t whole is inclosed in a casing 5' which is generally. of fabric though itmay be formed for example adapted to protect the resilient-material duringl'use against wear and tear.

Suc' substances as the following may be used as the resilient material, that is to say, gums, india-rubber, artificial rubber and rubber substitutes, stance with the addition of a suitable precipitant or coagulant;

The resilient'wmaterial ma be combine with a vegetable or minera body, animal or vegetable texturesor fibers, asbestos and so. forth...-,.i.

In order when mixtures of apply this resilient material, ues or gelatins and glycorother suitable sub-' of thin metal. which is only.

it may for example e der pressure, or even simply by running it into a mold into which has just been placed the metal plate which is to be coated with this material or which is to be covered comthis case the material is subjected to a' greater pressure so as to secure the desired greater density.

Referring now to Figs. 4 to 6, it will be seen that a single long band, strap or belt 6 is placed on the wearer, its ends 6 being passed around the waist portion of the strap and doubled back and fastened at any desired point, according to thesize of the wearer, by means of buttons 8 which engage in the holes 7 permitting of adjustment; these buttons at the same time form hooks.

On the part of the strap forming the front portion of the belt is arranged a-plate 9 provided with a hook 8 and suitable openings through which the belt is passed.-

On the back of the shield are secured three rings 10 (Fig. 3) adapted for engagement wit the three hooks 8 (Fig. 4) so that the shield may be worn as shown in Fig. 5.

It will be understood that the shape of the shield and its accessory members may be varied according to the use and method of attachment and. securing the same, without departing from the spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. Protective armoring adapted to resist bullets and shell splinters, and comprising a metal plate, a frame around said plate, a resilient material between theframe and the plate, a layerof resilient material on both sides of the plate and a casing around the frame and resilient material.

2. Protective armoring adapted to resist bullets and shell splinters, and comprising a metal plate, a frame around said plate, a

dense resilient material between the frame and the plate, a layer of resilient material on both sides of. the plate, and a casing around the frame and resilient material.

- 3. A body shield comprising a metal plate, a frame around said plate, a dense resilient material between the frame and the-plate, a layer of resilient material on both sides of the plate, an inclosing casing, rings on' the shield, and a strap having hooks for engaging with the rings. A
